Hey there! As a fellow purchasing manager, I totally get your concern about those '6-8 week' promises. Here are some specific questions you should ask to uncover whether they're quoting from actual inventory or just hoping their manufacturing capacity will magically align:
1. "Can you share your current inventory levels for this specific drive model?" - This gets straight to whether they have physical stock
2. "What's your current production schedule and capacity utilization rate?" - This reveals if they're actually manufacturing or just hoping to
3. "Are you sourcing any components that might have their own lead times?" - Critical for understanding if they're waiting on parts themselves
4. "Can you provide visibility into your raw material inventory for this product?" - Shows if they have the building blocks ready
5. "What's your historical on-time delivery rate for similar lead time promises?" - Past performance is the best predictor
6. "Do you have any current production runs for this model, and if so, when did they start?" - Gets specific about manufacturing status
7. "How do you handle unexpected demand spikes or production delays?" - Tests their contingency planning
The key is asking for specific, verifiable details rather than accepting vague promises. Suppliers with real inventory or active production lines should be able to provide concrete data. If they're evasive or can't give specifics, that's a red flag they might be quoting from 'phantom inventory'!
